哲水蚤目包括一些在海洋和淡水环境中最成功的浮游生物群。由于该类群的分类特征在形态学上的复杂性，其亚类和分类系统一直是复杂而有问题的。本研究以核核糖体RNA小亚基（18 S）和大亚基（28 S）基因以及线粒体编码的细胞色素B和细胞色素c氧化酶亚基-I基因为基础，建立了一个哲水蚤类桡足类的多基因分子系统学，包括7个总科29个科。这种分析比以前的研究更全面的家庭，分子标记的范围内，和解决的分类水平的广度方面。核糖体RNA基因的分歧模式被证明是显着的异质性之间的超家族，提供了一个可能的解释不同的结果，以前的研究。多基因系统发育恢复了一个单系的哲水蚤目，以及总科Augaptiloidea，Centropagoidea，Atypontioidea，Eucalanoidea，Spinocalanoidea和Clausocalanoidea。该遗传学与先前发表的形态学遗传学基本一致，包括例如，包括福氏科在内的长喙龙总科的扩大。(C)2011 Elsevier Inc.

The order Calanoida includes some of the most successful planktonic groups in both marine and freshwater environments. Due to the morphological complexity of the taxonomic characters in this group, subdivision and phylogenies have been complex and problematic. This study establishes a multi-gene molecular phylogeny of the calanoid copepods based upon small (18S) and large (28S) subunits of nuclear ribosomal RNA genes and mitochondrial encoded cytochrome b and cytochrome c oxidase subunit-I genes, including 29 families from 7 superfamilies of the order. This analysis is more comprehensive than earlier studies in terms of number of families, range of molecular markers, and breadth of taxonomic levels resolved. Patterns of divergence of ribosomal RNA genes are shown to be significantly heterogeneous among superfamilies, providing a likely explanation for disparate results of previous studies. The multigene phylogeny recovers a monophyletic Calanoida, as well as the superfamilies Augaptiloidea, Centropagoidea, Bathypontioidea, Eucalanoidea, Spinocalanoidea and Clausocalanoidea. The phylogeny largely agrees with previously-published morphological phylogenies, including e.g., enlargement of the Bathypontioidea to include the Fosshageniidae. (C) 2011 Elsevier Inc.
